Microbial lipases as virulence factors
Journal of Molecular Catalysis B: Enzymatic, 2003Abstract Up to now, lipases of microbial origin are known to be very useful in a palette of industrial applications. But it becomes more and more obvious that extracellular lipases also play a role during microbial infections. This review will focus on the virulent traits of these secreted enzymes from bacteria and fungi.

Microbial Lipases and Their Versatile Applications
2020Lipases are important biocatalysts and known for their versatile biotechnological applications. Lipases are well known as triacylglycerol hydrolases converting fats into simpler compounds as glycerol and fatty acids at the water-lipid interface and vice versa in nonaqueous medium.

Production and optimization of microbial lipase
Bioprocess Engineering, 1998Production of lipase by the newly isolated Pseu-domonas species has been optimised. Various parameters like initial pH, temperature, incubation period, effect of agitation, inoculum age, inoculum concentration were optimised. It was observed that modified GYP media with 72 hrs incubation, pH 5.5, at 37 °C in agitation conditions were optimum for growth

A Review on Microbial Lipases Production
Food and Bioprocess Technology, 2009This review paper provides an overview regarding the main aspects of microbial lipases production. The most important microbial lipase-producing strains for submerged and solid-state fermentations are reviewed as well as the main substrates, including the use of agroindustrial residues.

[The characterization of microbial lipases. 2. The determination of lipase specificity].
Die Nahrung, 1991Types of lipase specificity are as follows: Positional specificity; fatty acid specificity; stereospecificity; substrate specificity (different rates of lipolysis of different glyceride classes. The acylglycerol used for determination of lipase specificity must be so structured, that specificities are not confused and unambiguous results are obtained ...

Solvent stable microbial lipases
Biotechnology Letters, 2019Objective: This review examines on our current understanding of microbial lipase solvent tolerance, with a specific focus on the molecular strategies employed to improve lipase stability in a non-aqueous environment. Results: It provides an overview of known solvent tolerant lipases and of approaches to improving solvent stability such as; enhancing ...

[The characterization of microbial lipases. 1. The determination of lipase activity].
Die Nahrung, 1990In the selection of an appropriate method for activity determination of lipases existing technical equipment, kind of enzymes, number of samples investigated (e.g. in routine analysis), and expected sensitivity range have to be taken into account. Titrimetric methods and above all copper salt methods with their high detection sensitivity are the most ...

Glyceride synthesis by four kinds of microbial lipase
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1977Apart from their usual mechanism of action, lipases from Aspergillus niger and Rhizopus delemar also catalyzed the synthesis of glycerides from oleic acid and glycerol. Lipases from Geotrichum candidum and Penicillium cyclopium were inactivated by oleic acid, but were stable in the presence of casein, albumin or buffer of appropriate pH.

[Isolation of lipase of microbial origin].
Prikladnaia biokhimiia i mikrobiologiia, 1977By gel chromatography and polyacrylamide gel disc-electrophoresis the component composition of the culture liquid separated from the mycelium was investigated. After elution from Sephadex G-75 column lipase activity was concentrated in one peak. Out of 13 electrophoretic mobile protein components only one split trioleate.
